Break-Even ACOS Results
Total Cost = Product Cost + Shipping + Amazon Fees + Other Costs
Profit Per Unit = Selling Price – Total Cost
Break-Even ACOS = (Profit Per Unit / Selling Price) × 100%
Profit Margin = (Profit Per Unit / Selling Price) × 100%
Note: Your actual ACOS should be lower than Break-Even ACOS to be profitable.
Know Your Max ACoS Before You Lose Profit on Amazon Ads
If you’re running Amazon PPC campaigns, there’s one number you must know: your Break-Even ACoS (Advertising Cost of Sale). This calculator instantly shows you the maximum ACoS you can afford—before your ads start eating your profit.
Whether you’re launching a new product or optimizing existing ads, this free tool helps you bid smarter and protect your margins.
What is Break-Even ACoS?
Your Break-Even ACoS is the percentage of your product’s sale price that you can spend on ads without losing money. If your ACoS goes above this number, you’re running ads at a loss.

- Product price
- Cost of goods sold (COGS)
